Parker’s Metal Seals (C-Rings / C-Seals) are used for sealing of internal and external pressures in diverse aerospace and industrial applications where minimal leakage at extremely low or extremely high temperatures is of paramount importance. They are suitable for use with very high pressures and in aggressive media. Parker’s portfolio includes a wide range of available seal cross sections for challenging applications.

Metal Seals (C-Rings) are manufactured from nickel alloys and suitable for use at temperatures of up to 870 °C even at high pressures. These seals exhibit elastic recovery and can be electroplated for higher sealing performance. Parker offers diverse plating materials such as silver, gold, tin, PTFE and others for this purpose.

Product Benefits:

• Good elastic recovery enables use in cyclical temperature changes and flange separations.

• Temperature range from cryogenic up to 870 °C.

• Pressure range from vacuum to 524 MPa and higher.

• Large selection of cross sections.

• Available in all diameters from 6.35 mm to 3 m; tools available for many commonly used sizes.

• Suitable for use with uneven flanges.

• Various materials available for high-temperature resistance, good resilience and resistance against corrosion and fatigue.

• Large selection of coating/plating options.

• Circular, oval and other custom shapes available.
